DPF Cleaning at Home - 9 Chemicals Tested (Diesel Particulate Filter DIY Ash Cleaning)
Рет қаралды 1,061,500
Күн бұрынIn today’s video we test out 9 chemicals on an end of life, ash clogged diesel particulate filter at home. To do this test I first cut open an old DPF and cut it into small pieces, and then test each piece to see if the chemicals can dissolve the ash build-up. The chemicals tested are: Wynn’s Off Car DPF Cleaner, Drain Cleaner, Swimming Pool Acid, Dishwasher tablets, 32% Vinegar, Acetone based paint thinner, Brake Cleaner, Cola and Alloy Wheel Cleaner. Watch and find out! Please note that these kinds of chemicals are for cleaning a filter that has been removed from a car, and should not be used for cleaning a filter in situ. To see how these chemicals are used in an actual DIY cleaning process once the DPF has been removed from the vehicle, then follow along with this video called "The No Damage DIY DPF Clean": • The Non-Damaging DIY D... Warning: None of these chemicals should ever be added to your fuel tank.

Thank you Steven for creating this video. I have successfully restored a heavily blocked DPF from a Subaru using your Dishwasher Tab/Pool acid technique. Two months later, still working fine with no problems. The original cause of the blockage was sooty oil completely encasing the MAP sensor, and an intake boost leak. The car is running well, with performance and economy significantly improved. Cheers!

Tested and worked perfectly. Bmw 2007 E60 520d dpf removed from car, pre cleaned for about 30 mins. with 1L of mr.muscle drain unblocker (diluted with 1L of water) , this stage will remove grease mainly. After, i used 20L water + 5L brick acid HCL 34%, and let the dpf soak for about 3 hours. I give it a rinse with just a hose garden initially and after a jet wash with 2 bar pressure (no higher than that as you'll destroy your honey comb inside). Also keep your jet wash nozzle/lance at a 200mm distance from dpf honey comb. Water came clean after all this process and had a good flow from both sides. Dried the dpf for few days and reinstalled on the car. Before this diy clean my car was cutting off right after engine start as dpf was fully blocked. Now my dpf readings are: 4mBar at idle, 12mBar at 2000rpm and 42mBar at 4000rpm. Cost for replacing dpf to this 15 years old car is £1400 just the genuine part + labour to install it. Cost for diy this method is under £50 and some diy enthusiasm. My car has the dpf separate from Catalytic converter. Thank you for all your videos Steven. Nowhere on youtube you can't find such detailed explanation.

The irony of DPFs is hilarious. Save the environment by filtering out some particulates, while at the same time consuming almost double the fuel and halving the efficiency and life of the engine. Great video though, pretty enlightening. Coke is scary stuff.
@berczigabor 2 жыл бұрын
There's nothing ironic about the DPF, because its purpose is not to reduce emissions overall, but to reduce the *toxic* emissions by transforming them to essentially non-toxic substances. In that regard it's a marvelous invention, because it reduces toxic and cancer causing emissions with at least over 95% efficiency. Also your double fuel figure is off by a magnitude of two at the minimum. In reality DPF only increases fuel consumption by a few percents in the worst case (even less in most cases), which, again, is a very small price for not having to die of cancer or even just live with asthma and in constant smog in cities.

@@cg5138 For one, DEF (as in Adblue or urea mixed with water) has nothing to do with the DPF, and is used for a completely different purpose. It's not doing something with the DPF, albeit it's there - just like the DPF - to reduce poisonous emission, but a different kind of that: NOx gases, that can cause a wide variety of respiratory diseases. Also, DEF is produced as a byproduct of ammonia production, and its production is actually reducing the environmental impact of that. As for what's smart: smart would be if people would educate themselves about the DPF, DEF and similar stuff, before spitting out stupid statements about it, because for one these are there to save their lives and health, but also because only the really dull ones believe that all this stuff is built into cars not because of very good and valid technical and health reasons, but because of being part of a guvemah conspeerazzy to oppress them.

Thanks for this video. Ive just cleaned my 2012 Vivaro's DPF / DOC using dishwasher tablets first followed by oxalic acid alloy wheel cleaner. I had error codes on my dash 'Check Injection' and 'Check Emissions' which means DPF is blocked. The van failed last year's MOT with these warnings so the garage did a clean using aerosols with the DPF still on the van. This turned the warning codes off and got the van through MOT but warnings were back 1 month later. Watching your video gave me confidence to tackle it myself this year ahead of the MOT. I was really nervous about loosening the two manifold nuts to remove the DPF/DOC exhaust section as it's 11 years old, and manifold nuts of that age tend to like staying put. But a good quality socket and a bit of GT85 got things moving. I used an old dustbin to soak the exhaust in overnight with dishwasher tablets, and some frequent flushing through / agitation soon released a lot of soot. I would say this preliminary cleaning was most affective. Next I drained and rinsed then soaked overnight in oxalic acid alloy wheel cleaner. I'm not convinced this had a huge benefit considering the dishwasher tablets worked so well. Maybe if I'd skipped the dishwasher tablets and gone straight to alloy wheel cleaner then I'd be saying how wonderful it was. Thinking optimistically though, maybe the alloy wheel cleaner removed the important last 5% of soot from deep down in the DPF. Rinsing the DFP with freshwater took forever to remove the frothing. The flushing water would not run out without some frothing, even after about a million gallons! Not sure what's causing that, either the dishwasher tablet or the alloy wheel cleaner residue in the insulation. I had to call it eventually and run with it. I don't think the frothing would have ever stopped. I left the exhaust out in the sunshine for about a week to dry out (cant believe we got a week of sun in UK!). Then refitted. I didn't use the OBD to cancel the warning codes, instead I took the van for a good drive. Pulled over once after 15mins, turned off and on. 'Check Injection' warning had gone. Drove again for another 15 mins, off and on. 'Check Emissions' warning also gone. Alleluia, the dashboard no longer lights up like a Christmas tree. A week on, and all is good. runs great, no warning lights and the van could be a keeper for another ten years. The only thing I'm concerned about is the Emissions Test at next MOT in few weeks time. Has the dishwasher tablets or alloy wheel cleaner affected the metals on the DOC and that no longer processes CO correctly? I hope its OK or else expensive replacement. (By the way, despite 1 week in the sunshine to dry out the exhaust, there was still quite a lot of moisture vapor coming from the exhaust on its first run. Only visible when stationary on tickover. It must have been lingering in the insulation. If doing it again, I'd be tempted to leave a hair dryer running through the DPF / DOC exhaust for a few hours also before refitting.)

That possibly may have some positive effect depending on volume flow rate for a sustained period, but I think a lower pressure/higher volume air flow source would be better over a long period. A dry heated air source would be best. Borrowing the wife's hair dryer and letting that blow through for a few hours would work good. An update on my van and MOT test........ All good during the emissions test and passed. I hadn't ruined the DOC Cat and all my dashboard warning lights still off. Very happy!

Hi Steven, I really liked you`re videos. I found that the best combination to clean a DPF filter is a 2-mol Oxalic acid and Ethylenediaminetetraacetic acid in water. The materials are kinda cheap since you only need a few grams of each per litre and you can do a flush with the engine running. I`ve done this for about 4 times on my own VW Touareg in the last 3 years and the dpf is in best condition.

Hi Steven, I tried ALDI all in one dishwasher tablets (not family pack) and Super Alloy concept wheel cleaner (10-25% phosphoric acid, 25-50% hydrochloric acid as per data sheet). Condition of BMW DPF (520 d se2008) -before hand-fuel economy nearly doubled, car sounded juddery sometimes-fuel emission light on frequently-turbo failed a month ago-looks like fuel or something got into engine oil also as oil level increased after turbo replacement. I got the local mechanic to remove the DPF. Crushed 40 Aldi tablets into 15 litres of 40 degree water (15 litres covered my dpf fully) agitated every 15 minutes for two hours . No water flowed through dpf at the beginning - dpf was used for 306,000km. After an hour soot started appearing and breaking down. (Probably could have used 80 tablets as I think this is what you suggested. After two hours soot only was removed (No sign of ash). Washed out with water both directions before next phase of ash removal. Diluted wheel cleaner 1:4 adding acid (12 litres of water and then 3 liters of wheel cleaner ) to water 40 degrees also (kept the hands warm with the rubber kitchen gloves and disposable gloves under these -just in case with safety glasses). Agitated every 15 minutes for 1 hour 30 minutes. Rinsed out with water both directions until no ash seen, then water and washing up liquid, then final rinse with de-ionised water. Dried in oven at 50 degrees for 4 hours . Before the final wash I could see that when using the garden hose that if I placed the hose against a selected few dpf holes the water flowed straight through. I realise this may not be possible for others but this particular dpf allowed me to see both ends. I got the mechanic to re-install and re-set today. After engine warm up fuel economy back to normal. I bought the Altel AP200 unit also so I will check for glow plug issues etc tomorrow. Did test with wheel cleaner on some stainless steel screws beforehand some tarnished and other brands did not . The dpf case did not tarnish. Thanks for the help.

@@StevenBTuner I would imagine if you limit the fluid volume to say a litre or 2 of each stage or whatever volume the DPF itself would roughly take up then you wouldn't have any issue's on most cars as the amount of pipe from turbo to DPF would comfortably take up way more than a litre on most cars, not to mention the turbo's are always higher than the sump/tailpipe height to allow proper turbo oil drainage so the fluid would 99.999% probably drain out of the tailpipe first, sure, i get that you can't account for the human stupidity factor like someone on a steep hill with front facing down but there's always the "disclaimer" option at the start of the video as well, explain possibly risks, video for info purposes only, do not try if you have an IQ lower than room temperature inside a freezer combined with a lack of common sense to match etc lol

I'm hearing you! :-) A reasonably strong phosphoric acid sprayed in using fairly fine droplets could work like that. If it could be made to foam up somehow that might be even better. The process might be something like: spray in 200ml, wait 30 minutes, then spray in another 200ml, wait another 30 minutes, spray in a liter of distilled water then blow in some low pressure air (14psi / 1 bar) for 5 minutes to dry things out. Such a method could work really well as something done every 2 years or so to keep the filter in top condition.

@@StevenBTuner The pressure differential from the turbo exhaust port into the DPF (let alone from the turbo into the exhaust manifold) would prevent that, the turbo exhaust is always at positive pressure compare to the DPF or the exhaust which is at atmosphere. Otherwise, any exhaust gases would back-flow into the turbo or exhaust manifold as well, which would choke the engine.

Hi Steven, using acidic solutions only might be a bit of a gamble since acids promote the formation of emulsions and a permanent sludge if too much oil and soot present. I would suggest adding cationic surfactant to prevent sludge, promote active binding and removal of soot and the acid to remove ash. Go with something like Bezalkonium Chloride in the 1-5% range addition. (Anionic surfactant and alkaline chemicals are usually in dishwasher powder/tablets) You might be on to something here. Great experiment, no sane person would flush part of the exhaust system with coke though :D the added sugar will do more harm than good!
@StevenBTuner Жыл бұрын
Hi, all good points! In my other vid I do a full DPF clean as a 2 stage process - the first stage is to clean away the oily soot so that the 2nd stage acid wash can do its work.
@jonasduell9953 Жыл бұрын
@@StevenBTuner Yeah I thought of that too, using either hydrocarbons or something like HEATED! sodium hydroxide solution or commercial/restaurant grade glass detergent to take off the soot before attacking the ash. The surfactant idea is more about creating something like Steven's even more effective mystery wonder solution or concentrate (would buy!!). Why do two soak and rinse cycles if you can make the acid work reliably for both with surfactants keeping the sludge/emulsion particle size controlled and small while the acid is happily eating away at the ash :) Commercial grade dishwashers are doing basically the same but with an alkaline solution. For plates, the wash cycle detergent is basically potassium hydroxide with added surfactants in the ~5% range to deal with fat/emulsion, glassware only detergents are just potassium hydroxide solution (this is why coffee cups with milk remains, very greasy lipstick prints and plates don't properly clean up in glass washers). I work for a global manufacturer of commercial dish- and ware washing solutions and content like this really intrigues me acidic route if adjusted right can result in a bucket of pH ~7 neutral watery suspension of ash, salts and soot particles. Mildly acidic one-cycle solutions with surfactants shouldn't be a problem either. Time to check environmental legislation I guess :D I'd definitely take that route considering the nasty fumes and environmentally unfriendly nature of hydrocarbon based solvents ending up being toxic waste when contaminated.

Having the HCL and NaOH react together at the end to form water and salt is definitely a plus. You can then filter out the remaining particles with a coffee filter :-)

The red residue is probably the cerine used by Peugeot as catalyst added to the fuel, to bring down the combustion temperature from 550 to around 450 C My Peugeot 508 - 2012 had the DPF completely plugged, so we cut it open to clean it as it came entirely welded, contrary to other DPF models which can be opened. When we inspected the filter, it had very low amount of black ash residue, compared to the red ash which was all over the DPF walls, so it was basically plugged with cerine. We ended up removing the DPF all together and reprogramming the car to work without EGR and DPF.

The red residue is probably Nitrogen Dioxide and ash mixture. The catalyst would have taken care of this gas.

We have a fleet of machinery (cat, komatsu, kubota, ect.) We've had great luck simply pressure washing out the dpf filters. Once any of the machines start frequent regens, or will no longer clean them selves effectively through a normal or forced regen, we will pull the dpf off and disassemble them. Then use a low pressure pressure washer (maybe 1500psi) and wash them out from both directions with just water. This seems to clean 90%+ of the soot. The machines always run better and generally take way way longer to even do the next regen because they're so cleaned out it takes a long time to build enough soot back up to need to regen. The first couple times we tried it we were pretty scared to mess something up. But now its become a regular thing and have yet to have an issue. Once the filter is washed out we will blow out with air, place in front of a fan to dry, then reassemble. Codes may or may not need to be cleared. We've done this process probably 40-50 times over the past several years. Its quick and free.

Finished the cleaning process on BMW N47D20A 177 hp. I used 10 liters of 10% NaOH and 7 liters of 10% HCl. Afterwards I did a lot of vigorous flushing with water and shaking like crazy. Overall about 200 liters of water. DPF backpressure before cleaning was 90-96 hPa and after it is 10-14 hPa at 2700 rpm, and 123-126 hPa -> 24-28 hPa at 3700 rpm. DPF pressure sensor was calibrated at engine off so the results are very accurate! As far is I compared these pressures on BMW forums the DPF after your cleaning method has backpressure as good as a brand new filter! Therefore I applaud you Steven and highly recommend this method. PS after first startup of the engine I was afraid it didnt clean well because the backpressure was as high as before of higher! But this was due to soke water being absorbed in the porous ceramic. After 15 minutes it dried nicely and the pressures are super low!
